Title: Silver knob Concert bass help
Post by: Kustomsunn on September 29, 2014, 07:47:14 pm

Hey Guys, I need some help. I have a Sunn concert bass silver amp made in 74'. The distortion does not work. Yes I grounded the RCA footshitch :-) I cleaned and tested the pots, the boost works but the distortion does not. Did serious testing of components and found nothing out of the ordinary. Really stuck here, any one have any advice?? The rest of the amp works well and makes me sad the distortion is not! HELP!!!!!
